MACHINE FOR REPAIRING CUES AND' THE LIKE.

Application filed. February 10, 1920.

To all whom it may concern.

Be it known that I, HENRY O. TAYLOR, a citizen of the United States, residing at Rockford, in the county of Vinnebago and State of Illinois, have invented certain new and useful Improvements in Machines for Repairing Cues and the like, of which the following is aspecification.

The primary object of the present invention is to provide a simple and novel machine for repairing billiard or pool cues, and more particularly, the points of such cues. In this regard, it is desired after a cue point or ferrule tip has been worn, broken off or become loosened, to turn a dowel or tenon on the end of the cue for the reception of a new point, and then to turn the new point to the same diameter as the end of the cue. My improved machine is designed to perform the e operations quickly and to a fine degree of precision, so that the new point will be effectually secured in position and will be neatly fit to the cue.

Another object of my invention is the provision of a machine of the character described, which shall be embodied in such simple and practical form as to enable eco nomical production thereof as a commercial article and which shall serve in a satisfactory manner the conditions and requirements of the trade.

Still another object is to provide a cueworking machine which shall be semi-automatic in its action in that after it is properly adjusted, it will, when put into operation, perform the desired turning with accuracy and precision.

I have also contemplated the provision of a cue-working machine having a suitable rotary chuck for holding a cue, and a cuttercarrying frame movable into and out of cutting relation with the cue carried by the chuck, and of means for revolving the cutter and regulating its approach to the cue, and consequently, the depth of cutting. In this connection, I have also aimed to utilize the cutter-driving movement to revolve the cue chuck in timed relation, so as to perform the turning operation with considerable accuracy.

Other objects and attendant advantages will be appreciated as the invention becomes better understood by reference to the fo11ow- Specification of Letters Patent.

Fig. 5, an enlarged sectional view taken on the line 5-5 of Fig. 4; and

Fig. 6, a fragmentary view of the near side of the cutter frame shown in Fig. 8, and showing the finished cutter gage in position.

My improvements are carried by a frame or bracket designated generally by character 7, adapted to be rigidly secured to a table or support in any suitable manner. The bracket is shaped to provide a cylindrical chuck barrel 8 disposed on a horizontal axis and a transverse end portion, at present in the form of upwardly reaching arms 9 and 10. Within the barrel 8, I have revolubly mounted a chuck of novel construction, peculiarly adapted to grip and revolve a billiard or pool cue for the purpose of properly presenting the small end thereof to a cutter which will be presently described.

The chuck consists of a spindle 11 revoluble in the barrel 8 and having an annular shoulder 12 engaging one end of the barrel and carryinga fixed spur gear 13 at the op posite end of said barrel, so that the same is held against lengthwise displacement. One end of the spindle has an internal tapered face 14, and the opposite end is internally threaded for the reception of a collar 15 having an internal tapered face 16, inclined oppositely to the face 14-. Between these tapered surfaces 1-1 andlG is interposed a pair of jaws 17 and 18, each relatively V shaped in cross section throughout its length so as to fit cues of different diameters. These jaws are held in cooperative relation by interfitting parts 19 and 20 which hold the jaws against relative lengthwise displace ment and also permit relative tilting movement between the jaws so that they may conform to the taper of the cue. A spring element 21 embraces and connects the jaws, tending to separate them. It will be obvious that with a cue disposed between thejaws s shown in Fig. 4, the same may be clamped upon the cue by screwing the collar 15 inwardly. This compresses the jaws at each end between the inclined faces 14 and 16 and clamps the jaws throughout their length to the cue. When the collar 15 is loosened the spring 21 will expand the jaws, permitting withdrawal of the cue.

Means is now provided for revolving the chuck, which consists of a spur pinion 22 meshing with the gear 13 and fixed to a shaft 23, which is mounted in the bearings 24 and 25. By means of a hand crank 26 fixed to the shaft 23, the gears 22 and 13, and consequently the chuck may be revolved.

I havenow provided a revoluble spiral cutter and shiftable cutter-carrying frame,

. by means of which the cutter may be instantly moved into and out of operative position, not only for the purpose of inspecting the work being done, but also for permitting certain adjustment which w1ll be presently described. The cutter-carrying frame is at present in the form of laterally spaced arms 27 and 28 pivotally mounted at oneend on the shaft 23 and joined at their opposite ends by a cross portion 29, the latter of which is equi ped with a handle 30, by means of which the frame may be raised and lowered upon and about the shaft 23. A spiral cutter 31 fixed to 'a shaft 32 interposed between and mounted upon the arms 27 and 28, is adapted to be revolved by means of spur gears 33 and 3 1 fixed to the shafts 23 .and 32 respectively. 1t will be obvious that upon turning the crank 26, the cutter 31 and the cue chuck will be revolved simultaneously, the cutter at a considerably higher speed than the chuck, and it will be further observed viewing Fig. 3, that the handle 30 may be swung in a counter-clockwise direction about the shaft 23, thereby withdrawing the cutter from operative position. Said operative position is determined by an adjustable screw or stop 35, passed through the outer end of the cutter frame portion 29 and adapted to seat upon.

the upper end of the bracket arm 10, as shown in Fig. 3. It will be observed from this figure that the cutter when in operative position is disposed directly above the one 36 and will cut to a depth determined by the adjustment of the screw stop 35.

In order to turn a dowel or tenon on the end of a cue, the latter is inserted through the chuck until the end to be turned down overlaps beneath the cutter 31 a distance equal to the length of the tenon. to be cut. This distance is determined by an adjustable stop 38, as will be obvious. To turn the tenon, the cutter frame is lowered onto the end of the one, and the crank 26 turned. This will revolve both the cutter and cue in the manner'mentioned above, and the end of the cue will be turned down to form a tenon of the requisite length and diameter as determined by the position of the stops 35 and 38. The cutter may be fed to the work by sufficient pressure on the handle 30. As the machine is set in this particular i11- stance, a tenon 39 will be turned on the end of the cue. It will bemanifest that in view of the fact that the one is revolved simultaneously with the cutter and in the opposite direction to the travel of the cutting surfaces, the periphery of the tenon will be a true circle. Thus, it is possible to very accurately fit a point or ferrule, as the case may be, to a tenon. l After the point has been secured on the one, it is desired to turn the point to the same diameter as that of the cue. To this end, 1 have equipped the cutter frame with a depth gage adapted to rest on the pe riphery of the one so as to determine the depth of this finishing cut. This is done in the present instance by means of a plate ll pivotally secured at 42 to the underside of the cutter frame arm 27, as shown in Fig. 6, and adapted to swing from an inoperative position crosswise of the frame under the cross portion 43 to an operative position parallel with and beneath the arm 2?. In this latter position, the free end of the plate 41 rides upon the projecting end of a screw 44 so as to be held taut in operative position and also so as to permit adjustment of the plate to vary the position of the cutter relatively to the cue. It will be observed that the plate 41-1 is so positioned that overlies and will rest upon the one in close proximity to the point, and will limit approach of the cutter to the point, so that the latter will be turned or finished only to the diameter of the one at its outer end. raising the cutter frame and swinging the plate 11 either into or out of operative position the machine may be instantly converted from a tenon cutting to a finishing purpose, or fol-any analogous use.

Attention is called to the fact that when the screw 35 is set for a given sized tenon, the resulting tenon will always be of uni form diameter, irrespective of whether the diameter of the cue bodies: vary.

It is believed that the foregoing conveys a clear understanding of the principles and objects of my improvements, and while I have illustrated and described but a single working embodiment thereof, it should be understood that various changes might be made in the construction and arrangement without departing from the spirit and scope of the invention as expressed in the appended claims, in which- I claim: V
